Include hash annotations in index & history pdf

1. make sure you have a 'current' cop
2. run SELECT * FROM rebuild_cites_annotation_symbols_for_node(NULL)
2. clear downloads cache
3. generate the index& history pdfs and go to last page

these are the original hash annotation keys:
index: https://www.dropbox.com/s/4owcmcaouwu9vos/Key_to_%23_annotations_%28flora_only%29.pdf
history: https://www.dropbox.com/s/onsbaih9kl45jcq/Historical_summary_of_annotations.pdf

NOTE: the historical hash annotations will appear in incorrect order and with missing 'valid from' dates, because we don't have that data atm.
